Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, specifically to an environmental monitoring water sample filtration device. Background Technology

[0002] Environmental testing refers to the scientific measurement and evaluation of various elements in the natural environment or a specific environment to ensure that the environmental quality meets certain standards and requirements. A water sample filtration device is a device used to purify water. It removes impurities and harmful substances from the water through specific filter materials to improve water quality. Water samples are also filtered in environmental testing to meet subsequent treatment requirements. However, existing environmental testing water sample filtration devices do not have a cleaning function. After long-term use, the filter screen is prone to clogging, which affects the overall filtration effect. Furthermore, they do not have the function of stirring the water sample and reagents during filtration. Therefore, we propose an environmental testing water sample filtration device. Utility Model Content

[0003] The purpose of this invention is to provide an environmental water sample filtration device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An environmental water sample filtration device includes a filtration unit with support rods around its bottom perimeter. An inlet is located on the top left side of the filtration unit, and a drain pipe with a control valve is located on the bottom left side. A motor is positioned at the top center of the filtration unit, with a motor shaft extending through the bottom of the motor shaft to the top center of the filtration unit's inner cavity. A transmission rod is located at the bottom of the motor shaft. A filter screen is located at the top of the filtration unit's inner cavity. A left crossbar is located on the left middle of the transmission rod, with bristles evenly distributed at its bottom, the bristles adhering to the top of the filter screen. A right crossbar is located on the right middle of the transmission rod, with a scraper at its bottom, the scraper adhering to the top of the filter screen. The bottom of the transmission rod extends through the filter screen to the bottom of the filtration unit's inner cavity. A connecting rod is horizontally positioned at the bottom of the transmission rod, with vertical rods on both the left and right sides of the bottom of the connecting rod, and stirring rods at the bottom of each vertical rod.

[0006] Furthermore: the top of the front face of the filter device is provided with a slot that matches the filter screen, and the top of the front face of the filter device is covered by a matching arc-shaped cover plate. Bolts are provided around the front face of the arc-shaped cover plate and the front face of the filter device.

[0007] Furthermore: the filter device is configured as a cylindrical filter device, with a cleaning port on the top right side of the filter device, and a matching sealing cover on the right side of the cleaning port.

[0008] Furthermore: the top of both the left and right sides of the inner cavity of the filter device is provided with a locking block, and the locking block is located below the filter screen. The bottom left and right sides of the filter screen are provided with a locking groove that matches the locking block.

[0009] Furthermore: a through hole matching the drive rod is vertically installed at the top center of the filter screen, and plug-in blocks are provided on both the left and right sides of the rear end face of the filter screen. Connecting holes matching the plug-in blocks are provided on both the left and right sides of the top of the rear end face of the inner cavity of the filter device.

[0010] Furthermore: an observation window is provided at the bottom of the front end of the filter device, and a reagent addition port is provided on the top right side of the filter device.

[0011] Furthermore: the angle between the left and right crossbars and the transmission rod is set to 90 degrees, and the left and right crossbars are set parallel to the filter screen.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This environmental water sample filtration device works as follows: Water enters through the inlet and is filtered through a filter screen. As the water passes through the screen, a motor drives a transmission rod via its shaft. This rotation simultaneously rotates the left and right horizontal bars on either side of the top of the filter screen. The rotating horizontal bars, along with brushes and scrapers at their bottoms, clean away accumulated debris from the top of the filter screen, preventing clogging. A cleaning port is located on the top right side of the device, allowing for the removal of debris from the filter screen. During water filtration, the motor, through the interaction of the motor shaft and transmission rod, drives a connecting rod. This connecting rod, in turn, rotates the vertical rod and stirring rod, effectively mixing the reagents and water. Attached Figure Description
